With no alternatives, the Argentine Navy considers decommissioning the Super Étendard Modernisé fighters acquired from France in 2019
Zona Militar – Throughout 2025, news regarding the Argentine Navy’s Super Étendard fighters has been scarce, with no mention of them by naval authorities or in the Management Reports submitted by the Chief of the Cabinet of Ministers to the National Congress.

Sea Dragons: Special Operations and Chinese Military Strategy
China Maritime Studies Institute – As China continues to rise as a global sea power, its maritime strategy continues to evolve. Among these critical evolutions is one of the People’s Liberation Army’s naval special operations forces’ most elite units: the Sea Dragons. A small yet highly specialized unit, the Sea Dragons entered the global spotlight and international consciousness with the 2018 film Operation Red Sea, raising several questions for Chinese naval experts. What does Chinese military strategy and doctrine require of special forces, and specifically naval SOF, to be able to accomplish the mission, particularly along the Taiwan Strait and in the South China Sea? What are their capabilities and limitations? What real-world experience do they have and how might they be employed in the future? This volume attempts to answer those questions and many more regarding one of China’s more enigmatic units and its role in future peacetime and low-intensity conflicts.
A British carrier group is coming to the Pacific—with doubts looming over it
The Strategist – The British carrier force faces obstacles. The only kind of fighter that the carriers can operate is the F-35B, which can make short take-offs unassisted by a catapult and can land vertically, not needing arrestor wires. Britain doesn’t have enough F-35Bs, and there’s a serious risk that the price of buying them will rise steeply.
Meanwhile, the ships rely on helicopters for carrying air-surveillance radars aloft, whereas some kind of aeroplane, with greater altitude and endurance, would be far better for the task.

BlueWhale™ – A True Submarine Force Multiplier
Naval News – Seafaring nations face unique challenges in ensuring the safety, security and sovereignty of their nautical frontiers. Even in times of tranquility they must guard against threats such as terrorism, smuggling, illegal fishing, natural resources theft, and uncontrolled mass immigration. And when conflict does arise, these nations must have anti-submarine and anti-surface vessel warfare capabilities to defend against naval incursion or attack. Even before the outbreak of open hostilities, it is imperative that they be able to detect and track hostile naval forces engaged in intelligence gathering and other covert activities.
